AI Technical Summary
Technical Problem
Existing jawbone retraction devices require penetration of skin tissue or exposure inside the mouth, increasing the risk of wound infection, affecting appearance, and potentially causing facial nerve damage.
Method used
A jawbone traction device is designed, which uses a magnetic drive component and a transmission component. It is completely implanted into the skin tissue of the cheek. The screw is rotated by a magnetic control handle to avoid direct contact with the skin. The transmission component stores and releases energy to adjust the traction force and achieve jawbone opening.
Benefits of technology
It avoids wound infection and facial nerve damage, is safe and convenient to operate, reduces pain, and achieves a slow bone regeneration effect.

Abstract
The jaw traction device comprises a jaw tractor and a magnetic control handle, the jaw tractor is used for being completely implanted into cheek skin tissue and comprises a support, a lead screw, a fixed traction plate, a movable traction plate, a magnetic driving assembly and a transmission assembly, and the fixed traction plate is arranged on the support; the screw rod is rotationally arranged on the bracket, and the movable traction plate is screwed on the screw rod; the magnetic driving assembly is connected with one end of the lead screw through the transmission assembly. The magnetic control handle is located outside the cheek skin tissue, and when the magnetic control handle is close to the magnetic driving assembly, the magnetic driving assembly can rotate under the magnetic traction of the magnetic control handle so as to drive the lead screw to rotate around the axis of the lead screw through the transmission assembly, so that the movable traction plate is driven to move along the axis of the lead screw; the transmission assembly is used for storing and releasing energy output by the magnetic driving assembly.
